Mexico became Cuba's main oil supplier last year due to the US blockade on Venezuela. Mexico’s state oil company, Pemex, has backed out of a planned oil shipment to Cuba, the country’s president appeared to confirm. The move comes after President Donald Trump insisted that “zero” oil would be sent to the island, and follows reports that Washington plans regime change there by the end of the year. Reuters reported last week that the Mexican government was reviewing whether to continue sending oil to Cuba, fearing potential reprisals from the United States.
